Energy storage systems (ESS) are being increasingly installed alongside renewable energy generation to smooth out the intermittent power and facilitate the modernization of the grid. ESS are a key distributed energy resource which can deliver active and reactive power to guarantee power quality and reliability. Battery Energy Storage Systems (BESS) is one of the fastest growing forms of storing energy, as it is flexible and easy to deploy, exhibits a short response-time and perfectly ties in energy distributed grids. Energy Storage Systems are emerging as a central building block of the expanding smart and distributed energy grid, either in residential (~ < 10 kW), commercial (~ < 150 kW) or decentralized utility-scale (~ > 150 kW) applications.

E-mobility is accelerating as well the proliferation of Energy Storage Systems (EES). Firstly, storage systems are essential to support the high peak powers and energy demand in ultra-fast EV charging stations. Secondly, Battery Energy Storage Systems (BEES) are to benefit from the reuse of EV batteries that at the end of their lifecycle do not fulfill the automotive requirements any longer. The drastic drop in the price-per-kW of battery technology will further drive sustainable and long-term growth for BEES.
